Not glued, not forged

IIRC rikizai is welded during rolling, but not forged. The grain structure is therefore ~isotropic, which sacrifices many of the advantages of traditional Japanese construction. I for one don't find the couple Tsunesaburos that I use to be superior to my solid/Western irons (though admittedly those are mostly PM steels at this point).

There's no adhesive in existence that could stand the required processing and use, so purge that idea from your mind :-)

If I could make one change to Western plane makers' alloy selection, it would be to stop using A2. Modern sintered steels have similar or better mechanical properties with much finer grain structure, so there's simply no reason to use it any more.
